Along with traditional fossil energy worsening shortages, the development and application of regenerative resource more and more receives people's concern. As important regenerative resource, solar energy power generating is gathered around and is held out broad prospects. The high altitude localities sunshine-durations such as plateau are long, and atmosphere is thin, air cleaner, and solar radiation is strong, and day and night temperature is larger, has abundant solar energy resources, possesses the good condition of utilizing photovoltaic generation. Due to the deficiency of the protective capacities of conventional photovoltaic assembly to ultra-violet radiation, be difficult to ensure in highlands its normal power generation within quality guarantee period.
In high altitude localities, because intensity of sunshine is large, especially illumination middle-ultraviolet lamp intensity is better than in low altitude areas such as Plains, and the situations such as aging easily appear in conventional photovoltaic module, and dusty wind weather and larger day and night temperature can cause photovoltaic junction box cracking. In addition, the longer snowfall time causes assembly surface accumulated snow also can affect the assembly generated energy of the whole year. Therefore, conventional assembly can not meet the requirement of special climate condition. The photovoltaic module that research and development possess special nature for varying environment condition is by the trend and the direction that are following assembly development.
Summary of the invention
For the problems referred to above, the object of this invention is to provide a kind of photovoltaic module that is suitable for high altitude localities, avoid the problems such as UV-induced material aging, component failures.
For solving the problems of the technologies described above, the technical solution used in the present invention is:
A kind of high altitude localities photovoltaic module, comprises the glass, an EVA layer, solar battery sheet, the 2nd EVA layer and the backboard that stack gradually from top to bottom, and described the 2nd EVA layer is the high cut-off of uvioresistant EVA layer.
Preferably, described glass is the anti-reflection coated glass that surface is coated with nonpolluting coating.
Preferably, on the upper surface of described backboard and lower surface, be coated with fluorine-containing layer.
Preferably, described photovoltaic module also comprises the terminal box that is arranged on described backboard lower surface, and the rated current of described terminal box is 13 ~ 17A, and rated voltage is 1200 ~ 1800V.
More preferably, the degree of protection of described terminal box be IP68 and more than.
Preferably, described photovoltaic module also comprises aluminum frame, and described glass, an EVA layer, solar battery sheet, the 2nd EVA layer and backboard are installed in described aluminum frame.
Preferably, a described EVA layer is high EVA layer thoroughly.
The present invention adopts technique scheme, tool has the following advantages compared to existing technology: be applicable to the high altitude localities such as plateau, the permanently effective problems such as UV-induced material aging, component failures of avoiding of this assembly energy, can make full use of the abundant illumination resource in highlands.
Brief description of the drawings
Fig. 1 is the structural representation of a kind of photovoltaic module of the present invention.
In above-mentioned accompanying drawing:
